How inhabitants of a city can take part in the definition and the “co-gestion” of public policies regarding commons patterns

My paper will focus on the legal mechanisms that would allow the inhabitants of a city to participate in the definition and management of public policies applicable to the city or their neighbourhoods in urban areas. How communities of inhabitants and actors can organise themselves to co-construct and co-manage these policies with the public authorities (or manage without). Using example of Marseilles, I will look at the obstacles and levers. The paper will also try to see how the existing system can be improved from other European examples.
